If you have access to the original project files on your PC but are locked out of the editing environment, some versions of MCGS allow you to view "Project Information" via the configuration tool, which might reveal hint metadata or user lists. C. Hardware Reset (The Last Resort)

Maintain a secure, offline log of all engineering passwords.

In the realm of industrial automation, the HMI serves as a critical bridge between human operators and machine logic. A primary pillar of its operational integrity is its password management system , which ensures that only authorized personnel can access sensitive configurations, modify parameters, or oversee critical processes. Hierarchical Security and Authority Levels

Determine if the password screen is part of the custom HMI project or the system itself. If it's part of the project, you must contact the original equipment manufacturer (OEM) as these are unique to the application .

For security compliance, passwords should be updated periodically. Engineers can build a dedicated "Password Management" screen into the HMI using system variables, allowing authorized operators to change their passwords without needing a PC or software access. Using Built-in System Functions

Note: It is industry standard best practice to change these defaults immediately upon installation to secure the machine. 3. How to Reset/Recover MCGS HMI Password

Always change factory-default passwords during the initial commissioning phase of the machine.

The Ultimate Guide to MCGS HMI Password Management: Recovery, Reset, and Best Practices

Are you trying to a lost password, or are you configuring a new security system ?

A significant aspect of MCGS password management involves the recovery of lost credentials—a scenario frequently encountered by maintenance technicians. Because MCGS project files are compiled and encrypted, simply opening a file to view the password is not possible without specialized tools or the original source code.

When commissioning a new MCGS HMI or working with a factory-reset unit, developers often look for default credentials.

Losing an engineering or runtime password is a common bottleneck in factory maintenance. Depending on your situation, use one of the following validated recovery paths. Method 1: The Project Backup Recovery (Best Practice)

Common super passwords include specific, date-related codes (e.g., 180101 or codes found in MCGS support documentation based on the system date). Method 2: Reset via Engineering Software (MCGSPro) If you have the source project file: Open the project in the MCGS development environment. Navigate to the settings. Redefine the password and download the project to the HMI. Method 3: Factory Reset / Data Clearing

Set during the project compilation phase. This password prevents unauthorized users from retrieving the compiled project from the physical HMI screen via USB or Ethernet.
